How Does the Gp32 Protein Facilitate Both Stabilization of Single-Stranded

Multiple Choice

How does the gp32 protein facilitate both stabilization of single-stranded DNA as well as its renaturation to double-stranded DNA?

A) gp32 is an enzyme and thus its reaction of separating DNA strands is freely reversible
B) gp32 binds only to regions of high A and T content so hydrogen bonding is reversible
C) gp32 displays cooperativity in binding to single stranded DNA
D) the gp32 C-terminal domain acts as a switch between weak and strong single stranded DNA binding
E) none of the above
